Abstract: Systems and methods for routing media packets between a plurality of processors and a digital signal processor (DSP) are disclosed. An exemplary device comprises: an egress processor; an ingress processor; conversion logic; and a DSP configured to transcode a payload in the packet. The ingress processor is configured to change a first layer-2 header of a received media packet to a second layer-2 header. The second layer-2 header includes a DSP address and an egress processor address. The first layer-2 header has a first format and the second layer-2 header having a second different format. The conversion logic is configured to change the second layer-2 header to a third layer-2 header, and to change the third layer-2 header to a fourth layer-2 header including the egress processor address in the first format. The third layer-2 header includes the egress processor address in the first format.

Abstract: Systems and methods for redundancy in a network device are disclosed. An exemplary network device comprises: a plurality of data forwarding elements (DFEs); and a redundant control plane. The redundant control plane comprises: an active control processor for configuring forwarding operation of each of the DFEs; an active layer-2 switch coupled to the active control processor and to each of the DFEs; a standby control processor; and a standby layer-2 switch coupled to the standby control processor and to each of the DFEs. The active control processor is programmed in a full-mesh so that the active control processor is in communication with each of the DFEs. The standby control processor is programmed in a full-mesh so that the standby control processor is in communication with each of the DFEs.
